Question 61
2 marks · Normal
Answer and see the solution →The velocity–time graph of a car shows that its velocity increases from 5 m/s to 25 m/s in 10 s. Calculate the acceleration of the car.
Question 62
2 marks · Normal
Answer and see the solution →Explain how you could use a velocity–time graph to determine whether an object is moving with uniform acceleration.
Question 63
2 marks · Normal
Answer and see the solution →A train slows from 24 m/s to rest in 30 s. Calculate its acceleration.
Question 64
3 marks · Normal
Answer and see the solution →A ball is rolled down a slope. The velocity–time graph for the ball shows a straight line with a positive gradient. Explain what this tells you about the ball’s acceleration and movement, using ideas from Galileo’s experiments.
Question 65
3 marks · Normal
Answer and see the solution →A toy car moves in a straight line. The velocity–time graph for the car is shown below:
Velocity–time graph for a toy car (a)[1 mark]Calculate the gradient of the graph.
(b)[2 marks]State what the gradient represents about the car's motion.
Question 66
2 marks · Normal
Answer and see the solution →A velocity–time graph for a moving object is curved upwards. Explain what this shape tells you about the object's acceleration.
Question 67
4 marks · Normal
Answer and see the solution →A sprinter runs a race. The velocity–time graph below shows her motion for the first 8 seconds of the race.
Figure 1. Sprinter's velocity-time graph (a)[3 marks]Calculate the total distance the sprinter travels in the first 8 seconds.
(b)[1 mark]Explain how the area under the graph represents the distance travelled.
Question 68
2 marks · Normal
Answer and see the solution →A cyclist moves at a constant velocity of 6 m/s for 35 seconds. Calculate the distance travelled using the area under the velocity–time graph.
Question 69
3 marks · Normal
Answer and see the solution →The graph shows the motion of a car as it accelerates uniformly from rest to 18 m/s in 6 seconds.
Figure 2. Velocity-time graph for a car accelerating (a)[2 marks]Calculate the total distance the car travels in the first 6 seconds.
(b)[1 mark]State the shape formed under the graph and briefly describe how you found the distance.
Question 70
3 marks · Normal
Answer and see the solution →A runner moves at first with increasing speed, then at a steady speed, and finally slows to a stop. Describe how her velocity–time graph would look, and explain how you would calculate the total distance travelled from the graph.
